The Schedule referred to in these Letters I-aten'c` and-making part o the same.

To 4allfwhom it mal/y conce/m:-

vBe it known that I, WILLIAM P. SPRINGER, of Oswego, in the county of Oswego, and State of New York,

have invented a new anduseful Improvement in Smnt- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a vertical section.

Figure 2 is a horizontal section, taken in the line x x `in iig. 1.`

Figure 3 is a horizontal section, taken in the line y in lig. 1.

lFigures 4, 5, and 6, are detail views.

Similar letters of referenceindicate like parts in allv the figures. s

In the accompanying'drawings* A A is the scouring-cylinder;

C c is the scouring-wheel;

D d is 'a double-suction blast-wheel; and

S S is the blast-wheel case, gs. 1 and 3,

The grain is admitted through spout E, fig. 1, to the scouring-cylinder A, and after working down through the scouring-cylinder, the grain falls into a chamber, F, below the beaters or scouring-wheel, igs.- l and 2, and from this-chamber it is pushed into sp0ut\,e, by arms or wings ff, which aieixed on the shaft G, and revolved therewith, and the grain having been deliv ered by the spout e, has passed through Ythe machine.

The scouring-wheel is fixed on the main shaft G, and

is madeup of a series of narrow outer beaters C c, and

of several wider ones, B B, nearer its centre. All the beaters have a backward inclination, which tends to sustain the grain longer in the cylinder A, and also helps the upward d ranght of air within the cylinder.

The blast-wheel is also -iixed on the shaft G, and is mode double by a horizontal web or diaphragm, it', figs. l and 3, which divides the wings of the wheel into two parts; D,`iig. l, being the upper part, and d, the lower part.

Outside ofthe cylinder Ais an annularchamber, H H, figs. 1 and 2. The lower part, d of the blast-wheel, draws air from this said chamber H, as indicated by arrows 2, andthe upper part, D, draws air from the inside of the scouring-cylinder, bymeans of a tube, I, which connects the open centre ofthe blast-wheel with the upper end of the scouring-cylinder.

Air passes into the pipe c as the grain is coming out, and passes through the grain which is being agitated in chamber F, by the wings f f, and a portion of this air then ilows up through thegrain in the scouring-cylinder, and into pipe I, and thence to the upper blast- `wheel,l while the other portion of 4air flows outward,

through the slotted sides ofthe cylinder' A, into chamber H, and thence to the lowerblast-wheel, as indicated by the arrows 2.

i'he chamber H does not receive all of its air through the slotted sides of the cylinder, but takes in aportion of it through holes h h, fig. 2, in the door of the chamber HJ lo regulate the draught, or power of the blast, an opening, R, fig. 1, is made in the casing over the blastwheel, and a valve, r," is provided, and when the blast is too powerful, the valve fr is opened more orless, as the case demands, and air admitted to the wheel, and by this means the force of theblast is regulated.

The scouring-cylinder is made in two parts, A A', fig. 2, and these parts are secured to each other by bblting theirwooden iianges a a together.

lFig. 4 shows an inside view of one of the parts of the scouring-cylinder. f These parts, A, are made up by fastening grooved segments j j to the flanges or wooden bars a a, and then dlling the grooves with short vertical hars J, and in this manner the body of the scouring-cylinder is built up.- v he bars J are made slightly broader at their ends than at their central parts, so that a narrow slot or opening is left between each of the two bars, to allow the -iinedust, &c., to be drawn through the sides of the cylinder, and he separated from the grain as itis being scoured; and these vertical bars 'J are also made a little more narrow on their outside faces thanthey are on the inside, as shown by J, iig. 2, to give the slots plenty of clearance.

The segments j, tigt 4, are grooved on their scouringfaces, and project slightly intothe chamber of the cylinder, so as to form narrow ribs or shelves, which dela the passage ofthe grain down the cylinder.,

The vertical bars J are dispensed with in the last or lower section of the scouring-face, and a diamondgroovedl face, K, substituted, which is very effective, as the grain drifts over this face in a zigzag manner, being continually thrown upand down, and constantly changing direction.

The step for the shaft G consists in a cup-shaped vessel, M, figs. 1, 5, and 6, in which is placed a removable box or step, N.

This box has an inclinednpper face, an, as seen in vertical section, iig. 6, which conveys all dirt, which comesout on to the upper part ofthe box, into pockets or spaces o o, (see top view, fig. 5,) which are formed by cutting away the sides of the box N.

After the shaft G is placed in the step, the cup M is lled with oil, so that the box N is fully covered by the oil, and a cape or cap, m, fig. 1, is then placed over the mouth of the cup M, to exclude dust therefrom. With this step so constructed, it willlr'un a Whole year, or longer, without any attention, and keep in perfect order. l

The inclined surface n carries all dirt away from the rubbing parts, and this dirt is secreted or deposited in the pockets o o. These pockets may be made in the sides of the cup M, instead of making them in the sides of the boieN.

When the box has become fouled by long use, it is removed, and the pockets cleaned ont.

By these means I obtain a machine that is durable, is easily controlled, anddoes its work in a thorough menner.

Having thus described my invention,

I do not claim, broadly, 2t scouring-cylinder made of grooved rings j and bnrsiJ, as I am aware that this is not new, but

I do claiml. The arrangement of the double fan D d i, scouring-cylinder A A, connecting-pipe I, and surrounding air-chamber H, all constructed and opemting substantin-lly as herein set forth.

2. The shaft G, provided with the beaters B Cnfan D d i, and sompers f, and resting in the block N n o, removablyttted in the box M, and covered with :t cap, m, in combination with the scouring-eyliinler A A and chambers H F, all substantially ns herein set forth.

The above specification of my invention signed by me, this 16th day of November, 1868.
